SpeQtral and Thales Alenia Space will work together to demonstrate quantum connectivity in space

On the occasion of IAC 2022, currently in Paris, the quantum company SpeQtral signed the MOU with Thales Alenia Space, and under the terms of the agreement, Thales will develop and develop quantum ground receivers for the SpeQtral-1 satellite of Singapore.

The SpeQtral-1 satellite, which is scheduled to be launched in 2024, is one of the first commercial satellites to use quantum technology to transmit encrypted information; in particular, the satellite will use confused photons that will act as encryption keys, making communications extremely safe.

Purpose of the first SpeQtral satellite

Quantum confusion

This phenomenon was first used in orbit in a Chinese experiment called QUESS in 2016, in which case Chinese scientists installed a device that generates pairs of photons in a confused state and then allows one of them to be transferred to the ground. At that point, two photons, hundreds of kilometres apart, allow the so-called QKD to be executed.

Simply put, photons become the key to encrypt messages, so it makes it impossible for a person without this key to decipher the message. Any attempt to intercept the key will cause the commie to be disturbed in such a way that the communicator can detect it.
